Why can’t I send emails while connected to VPN?

· ·

Can’t send or receive emails? Connecting to a VPN server can result in your email client not being able to send or receive emails. This can happen for several reasons:

  • The VPN provider you are connected to is blocking the ports the email client is using (SMTP).
  • Your email service is blocking access to datacenter IPs
  • Your email service is only allowing access to residential IPs
  • Your email service is only allowing access to IPs of its own country
  • Your email service is only allowing access to certain ISPs

This issue will only occur with email client applications and not with web browser email.

Steps to take if your email is not working

Change SMTP port

Access the settings of your email client and change the SMTP port to 587 or 465.

Change the VPN server

Connect to a different VPN server. The process for changing servers is detailed in your provider’s setup instructions.

DD-WRT Manual VPN Configuration

Disconnect from VPN

Disconnect from VPN on the FlashRouter and use your ISP Internet connection when using email.

Dual router setup users can leave the VPN running on the FlashRouter and simply connect to the other router’s network when using email.

Contact your VPN Service Provider

In some cases if you contact your VPN service provider they will be able to give you access to a specifically requested e-mail service.

What is a DNS leak and how can I prevent a DNS leak in my router?

· ·

What is a DNS leak?

A DNS Leak is an instance where your ISP receives DNS requests despite being connected to a VPN tunnel.

How do I check if my DNS is leaking?

  1. Perform the extended test on DNSLeakTest.com. Be sure to do so on multiple web browsers for best accuracy.
  2. Here you should only find one server and your ISP should not be listed as your actual ISP.
  3. If your actual ISP is not listed there is no DNS leak.

How can I prevent a DNS leak in DD-WRT?

Check your device's browser settings

Updates to web browsers have added DNS settings capabilities, while this often makes your browsing experience more secure it can also effect the results of a DNS leak test. You can go into your browser’s settings and search for “DNS” and disable the DNS of the browser for more accurate DNS leak test results.

A simple web search for “DNS settings [browser name]” should return helpful information for finding the setting in your browser.

Adjust DD-WRT settings

1. On the Setup > Basic Setup page of the DD-WRT settings check the Ignore WAN DNS box.

This setting may not appear in older DD-WRT firmware builds. If it is not appearing for you, upgrade your DD-WRT firmware.

DD-WRT Check Ignore WAN DNS

2. Lower on the same page check the Forced DNS Redirection box.

DD-WRT Check Forced DNS Redirection

3. Click Apply Settings at the bottom of the page and then wait a full minute and power the FlashRouter off and back on. Reconnect to the FlashRouter’s network once it boots back up and then make sure you are connected to VPN by going to https://whatismyipaddress.com then perform the DNS leak test again.

Adding your VPN provider’s DNS servers to the router’s configuration can be helpful as well. The DNS servers are typically found on the VPN provider’s website or you can reach out to their team for a recommendation of what DNS servers to enter.

My VPN stopped working on my FlashRouter.

· ·

The VPN connection on the FlashRouter will not drop in most instances however if the VPN stopped working follow the steps below.

In order to use the FlashRouters Privacy App you need DD-WRT build 02/15/22 r48362 or 2/10/20 r42335.

Follow these instructions to upgrade the firmware to 02/15/22 r48362: How do I upgrade the DD-WRT firmware of my FlashRouter?

If you would like the fully featured FR Privacy App version with Simple Setup you must use firmware builds from 2/10/20 r42335.

  5. Make sure that you have any VPN/proxy apps and extensions turned off on all devices connected to the FlashRouter.

Why is my connection speed slower?

· ·

The encryption provided by a VPN connection almost always results in slower connection speed. In some cases you may have noticed that your computer or tablet was working faster when running a VPN client application or program, that is because a computer has a processor that is normally about 4-6x times as strong as a the processor on a router, and that is for managing a single VPN connection. A router has a smaller processor and is managing an entire network of devices. Encrypting an entire network does take considerable processing power.

Speed test results while connected to VPN are never going to be accurate. A speed test measures the rate at which a data packet travels from one server to another, however when you are connecting to VPN the data packets travel to an extra server where they are encrypted and then sent back into the route. We strongly recommend disabling the FlashRouter’s VPN connection when testing speeds to make sure there isn’t and issue with the router.

Connection Types

Ethernet: Wired ethernet connections will almost always be the most stable and reliable connection. To speed up your internet connection, use an ethernet cable to wire your devices to the FlashRouter.

Wireless (5.0GHz): The 5.0GHz WiFi frequency has less range than the standard 2.4GHz WiFi, but also transmits your internet connection at a significantly faster speed. If you were previously using the 2.4GHz network and experiencing slow speeds please connect to the 5GHz wireless network which should improve your speed.

Connect to the closest VPN server

Our supported VPN providers offer many servers in different countries and regions. If a server has slower connection speed we recommend connecting to the server closest to your actual location.

The process for changing servers is detailed in your provider’s setup instructions.

FlashRouters Privacy App

DD-WRT Manual VPN Configuration

Select a UDP server

UDP servers do not authenticate every data packets the way TCP servers do which results in faster connection speeds.

VPN provider server recommendation

Contact your VPN provider for a server recommendation that should provide the fastest speeds for you.

Why are streaming services blocked while connected to VPN?

· ·

Streaming services and VPN

Most popular streaming services such as Netflix, Hulu, and Amazon Prime block incoming VPN connections. This does not mean the VPN is not working, it simply means they have recognized you are connecting to a VPN server and filtered that server from being able to stream.

Below are several options for you to follow if you encounter this issue while connected to a VPN on your FlashRouter.

VPN provider server recommendation

Contact your VPN provider for a server recommendation that is not blocked by popular streaming services. Be sure to mention that you are connecting to VPN via a router instead of the computer client. If your VPN provider does not have a helpful suggestion or server recommendation please try the below options or contact us for a solution.

Bypass VPN by device

The FlashRouters Privacy App has a VPN bypass by device feature that can be used on devices dedicated to streaming.

Use SmartDNS

If access to streaming services not in your region is a higher priority for you then VPN encryption we recommend using a SmartDNS service on your FlashRouter to access the content you desire.

· ·

Router not connecting to the internet? Follow these simple steps!

  1. Make sure that you are not setting a WAN IP of 0.0.0.0 in the top right corner of your FlashRouter DD-WRT settings. If you do, then make sure your FlashRouter is wired correctly for Internet.
  2. Try power cycling your ISP modem, FlashRouter and any other router that may be in the setup. Power the modem back on first, wait for it to boot up fully, and then power the FlashRouter back on.
  3. Make sure you do not have Global Kill Switch enabled in the FlashRouters Privacy App and if you do make sure your VPN status is Connected.

How to fix an Unidentified Network or Limited Connection.

· ·

There are several common reasons that an Unidentified Network or Limited connection message may appear in your device’s network adapter.

  1. Wire the FlashRouter correctly for Internet access. Incorrect wiring is the most common cause of this issue. Make sure you are not wired into the FlashRouter WAN port for access, and make sure the FlashRouter is wired correctly to your main modem or router.
  2. Check that your connected device does not have static settings configured.
  3. Disable and reenable the wireless and/or ethernet adapter on your computer to refresh the network.
  4. Make sure you are not connected to multiple router networks at the same time, via WiFi and wired connection simultaneously.

Why are some of my devices not connecting to the internet?

· ·

  1. Make sure you are not using any device VPN device application or proxy on devices that are connected to the FlashRouter’s network as this can cause a conflict. Make sure the FlashRouter’s VPN connection is the only active VPN connection in your network.
  2. Check that static settings are not configured on your device.
  3. Certain devices require port forwarding rules to be properly setup before full connectivity. This may apply to devices like VOIP or smart cameras. If this is the case you may need to contact the manufacturer for more specific information.
  4. Check that the FR Privacy App feature for a device specific Kill Switch is not set for the device, and if kill switch is setup, then make sure the VPN connection is active.

Why is the internet LED red on my router?

· ·

Upon flashing the router from stock manufacturer firmware to DD-WRT firmware many buttons and lights on the router may have altered functionality. With DD-WRT firmware on certain devices a red internet/WAN light means a successful connection. While in factory firmware a red light denotes an issue with your internet connection. For anyone with DD-WRT firmware, this is not something you need to worry about as long as the internet functionality is in fact working.

Why is the power light on my FlashRouter blinking?

· ·

A slowly blinking power light means that the FlashRouter was somehow put into Rescue/Restore/Recovery Mode. This usually happens if the reset button was held down for too long.

This may also happen if you have incorrectly tried to update the firmware on your FlashRouter. The first thing to try is a simple reboot of the router to see if it exits restore mode.

If a reboot does not clear up the issue then try to reset and reconfigure your FlashRouter.

My 2.4GHz network is not showing up

· ·

If you ever have an issue with WiFi, you can always wire directly into the FlashRouter to verify and/or update your current WiFi settings.

Enter the recommended wireless settings

Our team has tested the wireless functionality for each FlashRouter that we offer and shared our recommended wireless settings in our Wifi Setup area. Replicate the settings for your FlashRouter model found on that page if the 2.4GHz is not showing.

Change the wireless channel

Navigate to Wireless > Basic Settings

Change the wireless channel setting for the 2.4GHz band that is not appearing. The most broadly compatible channels are 6 and 11.

CLICK APPLY SETTINGS

Refresh your device's network adapter

In rare instances the wireless adapter for your device may stop picking up WiFi networks and must be reset. This will be different for each device, that is why the best way to refresh your wireless adapter is to simply reboot any device in question and see if the adapter now picks up your WiFi networks.

Review wireless Status

Navigate to Status > Wireless

The readouts on this page can help tell if there are errors with the FlashRouter’s wireless. View our article on how to read the Wireless Status page for more information.

My 5.0GHz network is not showing up

· ·

Verify the device supports 5GHz

5.0GHz networks are not compatible with all devices so first make sure that you device’s wireless adapter supports 5GHz wireless frequencies.

If you are not sure, find out if your device support 5 GHz via Google search or by looking in the wireless hardware details in the device’s network settings. If you see Wireless a/b/g/n support then you have a compatible device. If you are missing the Wireless a then this means there is no 5 GHz support.

Enter the recommended wireless settings

Our team has tested the wireless functionality for each FlashRouter that we offer and shared our recommended wireless settings in our Wifi Setup area. Replicate the settings for your FlashRouter model found on that page.

Lower the wireless channel

Some devices do support 5.0GHz connections but not the higher channels that DD-WRT firmware offers.

Navigate to Wireless > Basic Settings

Lower the wireless channel setting for the 5.0GHz band that is not showing. Based on our tests the most broadly compatible channels are 36, 48 and 161.

CLICK APPLY SETTINGS

Refresh your device's network adapter

The easiest way to accomplish this is by rebooting your device as the settings to reset your adapter may vary on all types of internet connected devices.

Review wireless Status

Navigate to Status > Wireless

The readouts on this page can help tell if there are errors with the FlashRouter’s wireless. View our article on how to read the Wireless Status page for more information.

My WiFi password is not working

· ·

Keep in mind that passwords are case sensitive.

The preset DD-WRT FlashRouter WiFi password is Wireless#[First 5 characters of your router MAC]. The router MAC can be found on the bottom of your router. For e.g. if your MAC is 1459C07E70A8 then your WiFi password is Wireless#1459C

Verify wireless password

Connect an ethernet cable from a numbered port on the FlashRouter to a computer and access the FlashRouter’s settings.

Navigate to Wireless > Wireless Security

Check the Unmask box and note the wireless password that is entered.

Verify the wireless settings

Make sure that you have WPA2 Personal / AES set as the security settings for all bands. For some router models make sure the CCMP-128 (AES) box is checked for all bands.

Forget network on your device

Wireless devices usually offer a “forget” network feature to remove a wireless network from the saved information of the wireless adapter. If you have updated your WiFi password and are trying to connect on a device that previously used the old WiFi password then removing the wireless network and then trying to connect fresh can help with this issue.

Why did my WiFi SSID change to ‘dd-wrt’?

· ·

If you are seeing ‘dd-wrt’ in your available wireless networks instead of your regular FlashRouter24 and FlashRouter50 wireless network names (SSID) this means the router has been reset to default DD-WRT firmware settings.

Follow our instructions for Resetting and Reconfiguring your FlashRouter to get setup again.

Do not confuse your SSID being replaced by ‘dd-wrt’ with ‘dd-wrt vap’ appearing alongside your regular wireless network names.

If you are seeing ‘dd-wrt vap’ it likely means you did not rename your network when attempting to setup a guest network.

Why are devices disconnecting from Wireless?

· ·

If you find that wireless devices are routinely disconnecting from the FlashRouter’s network we recommend that you do the following:

  1. On the Wireless > Wireless Security page make sure you are using WPA2 Personal / AES as your security settings.
  2. On the Wireless > Basic Settings adjust the Wireless Channel. Select a wireless channel with less interference. The best channel will depend on your wireless environment.

Why is my WiFi signal weak?

· ·

If you find that wireless signal strength is weak while connected to the FlashRouter’s network we recommend that you do the following:

  1. Make sure that you have the external antennas fully connected to the FlashRouter.
  2. “Forget” the wireless network on the device and then rejoin with a fresh connection. This will be different for each device but can be effective.
  3. Make sure you are within an appropriate range for the network you are using. Keep in mind that a 2.4GHz network will always have better range than 5GHz networks. Devices further away from the router should use the 2.4GHz network.
  4. Interference from your wireless environment can also cause this issue. On the Wireless > Basic Settings adjust the Wireless Channel for the network you are experiencing the issue for. Channel interference is a likely cause for weak signal strength.
